NocoDB

NocoDB wraps your existing SQL databases in a familiar spreadsheet interface, turning PostgreSQL, MySQL, SQLite, and other relational databases into visual tables. You get Airtable-like features (forms, galleries, calendars, kanban views) without having to migrate data or pay per-record fees. The platform runs on your own servers or the managed cloud version, giving you control over infrastructure and data residency.

It's built for developers and teams who want Airtable's usability but can't accept vendor lock-in or recurring per-record pricing. NocoDB shines when you've already got a SQL database running and need a quick UI layer on top, or when you want to experiment with database-backed apps without rewriting queries yourself.
